Today, students of 17-18 years old from two schools, Colegio Vallmont and Sagrado Corazón de Jesús, came to ESAC really well prepared about space science. We had a really interesting conversations about dark matter, transits and the Cheops launch happened a little bit earlier.
Also, they did a great job calcullating the mass of Jupiter, just observing the movement of his biggest moons, Io, Europa, Ganymede and Callisto. Well done!
